Application filed November 8,1906. Serial No. 342,477.

To all whom it may concern: I

Be it known that I, ROBERT T. \VAKT, a citizen of the Uhited States, residing at Laurel Springs, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Electr0lier-HangerS, of which the following is a specification.

This invention relates to certain new and useful imprm'emcnts in ceiling couplings for electric light chandeliers, of which the following is a description.

With most chandeliers now in use, the same are suspended from the ceiling or wall by means of a tripod or crows foot threaded to the fixture and screwed to the ceiling. In hanging heavy fixtures, an extra man is required to hold the fixture while being fastened to the ceiling. In case the ceiling is not level, it is impossible to plumb the fixture, except by wedging around the tripod or crows foot, which is a very crude and often unsafe procedure, as the wedges work out and break the plaster allowing the fixture to hang loose.- This method requires much time and is.unsatisfactory. Another objectionable feature to this method of hanging, is that a sudden jar or side strain on the fixture will invariably loosen it.

To overcome the hbove noted objectionable features, the present invention contemplates the provision of a coupling, which will permit a single mechanic unas isted to hang a fixture, so that the same will be secure, sale and not liable to be displaced by a jar or strain, and above all plumb.

inference will be had to the accompanying drawing forming a part of this'spccil'ication and wherein like numerals of reference designate corresponding parts througl'iout the several views, in which:

Figure l, is a view in elevation of an electric light chandelier or fixture suspended from the ceiling, parts being shown in section, Fig. 2, is an enlarged view of the bottom of the ceiling plate, Fig. 3, is a top view of the same showing thc'fixture coupling entering the same, Fig. 4, is a fragmentary view similar to Fig. 3,

with the parts in a different position, Fig. 5, is an elevation of the coupling member of the fixture, parts being shown in section, and, Fig. 6, is a view similar to Fig. 5 of another form.

Reference numeral 1 designates the usual chandelier tube provided at its upper end with tcrior screw threads 2, upon which is threaded the wiring spider 3, formed in its opposite sides with the openings 4. As shown in Fig. 5, this spider is in the form of a nip 5O plo, such as 'is. carried in stock by dealers, and is threaded onto a boss 5 of the adjusting plate (i, where as, in Fig. 6, this spider 3 is cast integral with the adjusting plate 6 on the lower side thereof. This ad- ]usting plate is cast or otherwise formed with an integral T-shaped coupling member comprising a body 7 circular in cross section and provided with lateral arms 77.

Reiereuce numeral 8 designates a circular plate which is secured to the ceiling by screws passing through openings 8. A central boss 9 is cast integral with the lower face of the said plate. A round opening 10 extends vertically through. the center of said boss 9 and said opening is extended laterally as 11-11 on opposite sides whereby the opening 10 and branches l.l-1l thereof form a passage of the same shape as the cross section of the coupling member 7 and its'arms 7-7.

On its upper side, boss 9 is countersunk as at l2l2" on opposite sides of the central opening 10. These countersunk portions l212 are each in the form of a segment of a circle and begin at the branch openings lL-ll and terminate in seats 13-13 and shoulders The method of hanging a fixture in accordance with this invention is :1 follows: The plate 8 is secured by screws or other means to the ceiling, it being immaterial whether the ceiling is level or not. The chandelier tube 1 is then affixed to the coupling in accordance with the construction illustrated in Fig. 5 or that illustrated in Fig. 6. The .Trshaped coupling is then inserted into the opening 10 as illustrated in Fig. 3,

the chandelier tube and coupling are then turned one quarter of a turn when the arms 7-7 oi the coupling will engage the shoulders 14-14 and arrest further movement. At this point, the chandelier is allowed to move downwardly when the arms 7.7 will be received in said seats l313. In this position, the fixture will naturally assume a vertical or plumb position and all that is required to make this position permanent, is to tighten screws 6 in the adjusting plate (3 until their points come into engagement with the lower face of the boss 9. After these screws have been adjusted, it isdmpossible for the arms 7--7 to be jarred from their seats 13-13, as no vertical movement thereof is permitted, thus the coupling is rendered sale. 7

The insulated wires are passed through opposed openings lo lo in the plate 8 and their terminals led through openings 4 in the spider 3 and passcd'through the fixture tube 1 to the globes or other elements. On one side of each opening 15, is provided a pi\'oted jaw 18 serrated on one edge for biting engagement with the insulation 17 of the wire. Each jaw is locked in such biting engagement with the insulation by engaging over a pin 18.

In removing the fixture, the screws 6 are loosened, the coupling 7 lifted to raise the arms T 'i" irom the seats 13-43 and from this position, the fixture is turned until the urine 'Ji engage shoulders i ii4f and then the fixture is lowered, said arms 7--7 passing through branches ii il oi the opening 10.

What is claimed as new and novoi and desired to be secured by Lott r- Patent is:

1. A chandelier coupling colnfn-ising a ceiling plate, a. coupling :mmfiiiiii, iiL adjusting plate formed integral therewith. means simmering said coupling member-and adjusting plate with the chandelier tube, said ceiling plfilte being formed with a vertical diametrical opening for the reception oi the coupling niemlM-r, the upper face of the real in; plate ilihlg 'rrounlorsunk'on opposite sides of mild o r-ning 115d 'r'orim-ll with seats at right nngics to said (iiuinulrirnl oponlnx.
